I.O.I will celebrate its 10th anniversary with a special concert tour.

The group will launch "2026 I.O.I Concert Tour: LOOP" from May 29 to 31 at Jamsil Indoor Stadium in Songpa District, Seoul.

The tour will continue across major Asian cities. I.O.I is scheduled to meet fans in Bangkok on June 6 and in Hong Kong on June 20 and 21.

First Stage in About Nine Years

The upcoming shows mark I.O.I's first major stage in roughly nine years. The group last held a full concert during "Time Slip – I.O.I" in 2017, which served as their final performance before disbandment.

The new tour commemorates the 10th anniversary of the group's debut. It aims to reflect on past memories with fans while creating new moments together.

Meaning Behind "LOOP"

The concert title "LOOP" symbolizes connection and continuity. It conveys the message that a story once thought to have ended can begin again—representing reunion with fans and a new chapter.

The tour poster released alongside the announcement evokes I.O.I's signature atmosphere, featuring a pink color palette and emotional design.

Nine-Member Activities Planned

I.O.I will promote as a nine-member group ahead of the tour, including Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kim Doyeon, and Jeon Somi.

The group was originally formed through Produce 101 in 2016. After debuting in May that year, I.O.I scored consecutive hits with songs such as "Dream Girls," "Whatta Man," and "Very Very Very."

Following the conclusion of group promotions in January 2017, the members continued individual activities across film, television, and entertainment programs.
